Re: SQL FETCH -- RPG400-L

I pasted a piece from the Info Center.  Apparently you
can't ensure that the cursor is "sensitive" to db
updates.  SCROLL "may or may not have immediate
sensitivity" and DYNAMIC SCROLL is ignored when "The
ORDER BY or GROUP BY clauses specify columns which are
not all from the same table" which is the case in my
scenario.

Is this everyone else's experience or am I missing
something?

Thanks,

:

SCROLL 
Specifies that the cursor is scrollable. The cursor
may or may not have immediate sensitivity to inserts,
updates, and deletes done by other activation groups.
If DYNAMIC is not specified, the cursor is read-only.
In addition, the SELECT statement cannot contain a FOR
UPDATE clause. 

DYNAMIC SCROLL 
Specifies that the cursor is updateable if the result
table is updateable, and that the cursor will usually
have immediate sensitivity to inserts, updates, and
deletes done by other application processes. However,
in the following cases, the keyword DYNAMIC is ignored
and the cursor will not have immediate sensitivity to
the inserts, updates, and deletes: 
Queries that are implemented as temporary result
tables. A temporary result table is created when: 

The ORDER BY or GROUP BY clauses specify columns which
are not all from the same table
